DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Before the present invention is described in greater detail, it should be noted that like elements are denoted by the same reference numerals throughout the disclosure.

Referring to FIG. 1, the first preferred embodiment of an inflatable pad assembly 1 according to the present invention is shown to include a base member 12 and an inflatable pad 11.

In this embodiment, the base member 12 is in the form of a rectangular sheet, and has a top surface 121, a bottom surface 122 and a connecting end 123.

The inflatable pad 11 has opposite lateral layers 113, and a looped surrounding layer 112 interconnecting the lateral layers 113, cooperating with the lateral layer 113 to define an inflatable space 10, and connected to the base member 12. The looped surrounding layer 112 of the inflatable pad 11 has an outer leaning face that cooperates with the top surface 121 of the base member 12 to define a supporting area adapted to support a human body.

In this embodiment, the inflatable pad 11 is triangular in cross section. The looped surrounding layer 112 of the inflatable pad 11 has a first layer portion 1121, a second layer portion 1122 and a third layer portion 1123, wherein an angle (θ₁) between the first and second layer portions 1121, 1122 is greater than an angle (θ₂) between the first and third layer portions 1121, 1123. The connecting end 123 of the base member 12 is connected pivotally to a junction of the first and second layer portions 1121, 1122 of the looped surrounding layer 112 such that the inflatable pad 11 is operable so as to pivot relative to the base member 12 between a first position, where the first layer portion 1121 of the looped surrounding layer 112 has an outer surface that serves as the outer leaning face and where the second layer portion 1122 of the looped surrounding layer 112 has an outer surface that is coplanar with the bottom surface 122 of the base member 12, as shown in FIG. 2, and a second position, where the first layer portion 1121 of the looped surrounding layer 112 abuts against the top surface 121 of the base member 12 and where the third layer portion 1123 of the looped surrounding layer 112 has an outer surface that serves as the outer leaning face, as shown in FIG. 3. In other words, the inflatable pad 11 functions as a backrest when at the first position, and as a pillow when at the second position. The inflatable pad 11 further has a plurality of reinforcing belts 14 disposed in the inflatable space 10 and parallel to the lateral layers 113. Each reinforcing belt 14 has opposite ends connected to an inner surface of the looped surrounding layer 112.

FIG. 4 illustrates the second preferred embodiment of an inflatable pad assembly (1 a) according to this invention, which is a modification of the first preferred embodiment. Unlike the first preferred embodiment, the looped surrounding layer (112 a) of the inflatable pad (11 a) has a bottom layer portion (1121 a), and an upper layer portion (1122 a) that has an inverted U-shaped cross section, and an outer surface serving as the outer leaning face. The connecting end 123 of the base member 12 is connected to a junction of the bottom layer portion (1121 a) and the upper layer portion (1122 a).

FIG. 5 illustrates the third preferred embodiment of an inflatable pad assembly (1 b) according to this invention, which is a modification of the first preferred embodiment. Unlike the previous embodiments, the inflatable bad (11 b) is trapezoidal in cross section. The looped surrounding layer (112 b) has a first layer portion (1121 b), a second layer portion (1122 b), a third layer portion (1123 b) and a fourth layer potion (1124 b). The connecting end 123 of the base member 12 is connected to a junction of the first layer portion (1121 b) and the second layer portion (1122 b).

FIGS. 6 and 7 illustrate the fourth preferred embodiment of an inflatable pad assembly (1 c) according to this invention, which is a modification of the first preferred embodiment. In this embodiment, the base member (12 c) is in the form of a rectangular inflatable pad body that has top and bottom layers 124, 125, and a looped surrounding layer 126 interconnecting the top and bottom layers 124, 125 and cooperating with the top and bottom layers 124, 125 to define an inner inflatable space 20.

The inflatable pad 11 is disposed on and above the base member (12 c).

The inflatable pad assembly (1 c) further includes a connecting unit for interconnecting detachably the inflatable pad 11 and the base member (12 c). The connecting unit includes a zipper 13 that has two zipper halves 131, 132 engaging detachably each other. In this embodiment, the zipper half 131 is connected fixedly to a junction of the first layer portion 1121 and the second layer portion 1122 of the looped surrounding layer 112 of the inflatable pad 11, whereas the zipper half 132 is connected fixedly to the top surface (121 c) of the base member (12 c) using a reinforcing strip 15 disposed therebetween. It is noted that, in this embodiment, the inflatable pad 11 is operable so as to pivot relative to the base member (12 c) between a first position, where the outer surface of the first layer portion 1121 of the looped surrounding layer 112 serves as the outer leaning face and where the outer surface of the second layer portion 1122 of the looped surrounding layer 112 abuts against the top surface (121 c) of the base member (12 c), and a second position, where the first layer portion 1121 of the looped surrounding layer 112 abuts against the top surface (121 c) of the base member (12 c) and where the outer surfaces of the second and third layer portions 1122, 1123 of the looped surrounding layer 112 constitute the outer leaning surface, as indicated by imaginary lines in FIG. 7. In other words, the inflatable pad 11 functions as a pillow when at the first position, and as a backrest when at the second position.

FIGS. 8 and 9 illustrate the fifth preferred embodiment of an inflatable pad assembly (1 d) according to this invention, which is a modification of the fourth preferred embodiment. In this embodiment, the inflatable pad (11 d) is polygonal in cross section. The looped surrounding layer (112 d) has a first layer portion (1121 d) that is coplanar with the bottom layer 125 of the base member (12 c), a vertical second layer portion (1122 d) having an outer surface facing the surrounding layer 126 of the base member (12 c), a horizontal third layer portion (1123 d) disposed on and above the top layer 124 of the base member (12 c), an inclined fourth layer portion (1124 d) having an outer surface that serves as the outer leaning face, and an inclined fifth layer portion (1125 d).

The zipper halves 131, 132 of the zipper 13 of the connecting unit are connected fixedly and respectively to the second layer portion (1122 d) of the looped surrounding layer (112 d) of the inflatable pad (11 d) and the surrounding layer 126 of the base member (12 c).

FIGS. 10 to 13 illustrate respectively the sixth to ninth preferred embodiments of an inflatable pad assembly (1 e, 1 f, 1 g, 1 h) according to this invention, which are modifications of the fourth preferred embodiment. Unlike the fourth preferred embodiment, the inflatable pads (11 e, 11 f, 11 g, 11 h) of the inflatable pad assemblies (1 e, 1 f, 1 g, 1 h) are circular, elliptical, square and rectangular in cross section, respectively.

In sum, the inflatable pad (11, 11 a, 11 b, 11 d, 11 e, 11 f, 11 g, 11 h) of the inflatable pad assembly (1, 1 a, 1 b, 1 c, 1 d, 1 e, 1 f, 1 g, 1 h) of this invention is anchored to the base member (12, 12 c) such that undesirable displacement thereof can be avoided. Moreover, since the inflatable pad 11 of the inflatable pad assembly 1, (1 c) can be operated between the first and second positions, the inflatable pad assembly 1, (1 c) of this invention functions as either a bed with a pillow or a reclining chair.
